W80B Unable to upgrade firmware to the correct firmware

[dotinteractive]

My W80B has the firmware version 103.85.188.5 (Benelux version) and following the 3CX documentation I have to change it to 103.85.0.26.
When I try doing this I'm getting the error: Firmware update failed! Software limit Rebooting please wait ...

I didn't had this issue with my W80DM when I changed that device his firmware to the 103.85.0.26

My DM sees the W80B device but has the notification "Limited downgrade" in the status column on the "Base station settings" page.

Anyone that has a hint to solve this? Thanks!
